31 Jul 2020 | | Abstract: | Major elements such as Fe, Ti, Mg, Al, Ca, and Si play very important roles
in understanding the origin and evolution of the Moon. Previous maps of these
major elements derived from orbital data are based on mosaic images or
low-resolution Gamma ray data. The hue variations and gaps among orbital
boundaries in the mosaic images are not conducive to geological studies. This
paper aims to produce seamless and homogenous distribution maps of major
elements using the single-exposure image of the whole lunar disk obtained by
China’s high-resolution geostationary satellite, Gaofen-4, with a spatial
resolution of ~500 m. The elemental contents of soil samples returned by Apollo
and Luna missions were used as ground truth, and were correlated with the
reflectance of the sampling sites extracted from Gaofen-4 data. The final
distribution maps of these major oxides are generated with the statistical
regression model. With these products the average contents and proportions of
the major elements for maria and highlands were estimated and compared. The
results showed that SiO2 and TiO2 have the highest and lowest fractions in mare
and highland areas, respectively. Besides, the relative concentrations of these
elements could serve as indicators of geologic processes, e.g., the obviously
asymmetric distributions of Al2O3, CaO, and SiO2 around Tycho crater may
suggest that Tycho crater was formed by an oblique impact from the southwest
direction. | | Source: | arXiv, 2007.15858 | | Services: | Forum | Review | PDF | Favorites | |
